sracrrrcnrron forming part of Letters Patent is... 655,175, dated July3'1, ieoo. Application filed November 16, 1899. Serial No. 737,185. (Nomodel.)

To all whom/it may concern:

Be it known that I, CHARLES E. LINTON, a

citizen of the United States, residing at Saginaw, in the county ofSaginawand State of Michigan, have invented certain new and usefulImprovements. in Rotary Engines; and I do declare the following to be afull, clear, and exactdesc'ription of the invention, such as will enableothers skilled in the art to which it appertains same, reference beinghad to the accompany.- ing drawings, and tothe letters and figures ofreference, marked thereon, which form a part of this specification.

My invention is a rotary engine; and it consists of the combination,arrangement, and construction of the several parts whereby certainimportant advantages are'attained.

. In the drawings Ihave illustrated what may be termed a doublepistn.,-:-.2'. e., a piston with two steam-chambers,whereby the enginehas continuous pressureevia, one half live steam and the other halfexpansion, as hereinafter appears. I have also illustrated a reversibleengine. It will be obvious that the piston can be made single; but whenso made it will run a portion of the time on expansion entirely. It willalso be seenthat the piston may also be provided withwthreeor, moresteam chambers. This I, claim the right to do. i 1

In the drawings, Figure 1 is a vertical sec; tion on line w w of Fig. 3,but showing the entire casing. Fig. 2 is a section on line m w ofFig. 1. Fig. 1. Fig. 4 is a section 1. Fig. 5 is a section on line b bof Fig. 2 with the piston in different position. Fig. 6, is a section ofthe casing online a roof Fig.1. Fig. 7 is a section of the casing online e z of Fig. 1. r r

A is the piston,and consists of a metal wheel carried on the shaft 13,journaled in the casing or may be suitably supported in any other mannerand the sides of the casin g removed, as will hereinafter appear. Thepiston A is provided with two peripherical' grooves land 1, extendingnearly around the piston and the proper distances apart and from theedges of the wheel. These grooves are the steamchambers' of the pistonand, as stated, are not quite angular, the parts 2 and 2 of the on liney y of Fig.

piston lying between the ends of each groove respectively. These parts 2and 2' are upon opposite sides of the circumference of the piston andare integral therewith and form, as will hereinafter appear, thepiston-heads. These parts 2 and 2 extend at right angles to the bottomof the grooves, but are provided ,on each side with the'slopingwalls 3,extending from the top of the heads to the bottom the proper slope.

6 is the casing of the piston A. The outer surface thereof maybe of anyform, its inner surfacefitting the piston-wheel, and may be providedwith steam or otherpacking, none being shown in the drawings.

'7 and 7 are gates of the width of the grooves 2 and 2, and when in thegrooves completely block the same and may be so constructed as to besteam-tight.

As the piston A revolves the sloping walls 3 of the heads will engage agate and crowd it backward into a pocket 8 in the casing and as soon asthe head. has passed the-gate it will descend,its descent being retardedby the sloping walls 3, which, as previously stated, are on each side ofthe head. A spring 9 may be placed in the pocket 8 to make the downward.movement of the gate more positive.

10 is the opening of the live-steam pipe, 11 a valve in thelive-steamport, and 12 and 12 the live-steam ports and extend from the valve 11through the casing on each side of the middleithereof, respectively, andconnect .withthe small channels tively, on the inner surface of thecasing, but at the side of the piston-grooves 1 and 1' and not incommunication therewith, except at certain periods of the revolution ofthe piston, through the elbow-channelsin the piston 15 and 16, whichopen into the grooves 1, and 15 and 16', which open into groove 1',through the openings land 5 in the sloping walls 3 at the side of thepiston-heads 2 and 2'. The channel 13 extends from its connection withport 12 one-half the circumference of the easing. It will be seen thatas the piston revolves the channel 15 of the piston will be incontinuous connection with the channel 13 dur ing one-half of itsrevolution-4. c. during the time 15 ports with 13-and that steam will becut off from the piston as soon as 15 has passed 13 and 13', respectheend of the channel 13, and the piston will The groove 1 run on expansionuntil the head 2 has passed regulated from the outside of the engine, as

has exact duplicate connections to groove 1, and, its head 2 being onthe opposite side of the piston from the head 2 when the groove 1 is cutoff from taking steam, the groove 1 will commence to take IO steam fromthe channel 13 through the elbowchannel 16, and the engine will then berun by live steam in groove 1 and expansion in groove 1.

In order that the engine may be reversed, I

- construct the opposite side of the casing the same as the side justdescribed-viz., with channel 13 connected with port 12, and provide thepiston with elbow-channels 15 and 6', opening on opposite sides of theheads 2 and 2 from the opening of channels 15 and 16, which will connectthe grooves l and l with the port 12 through channel 13. 19 and 20 arethe exhaust port and valve of this side of the engine.

22, 23, and 25 is an arrangement of levers connecting steam-valve 11 andexhaust-port 20 and 20, whereby they may be adjusted so as to reversethe engine. 26 is a rack, in which the lever 25 may be locked whenadjusted.

the groove at In the engine, as illustrated, I have shown a meansforshortening the grooves 13 and 13, so that lesssteam may be used-viz. theplug 35 extending from outside of the easing into any desired point andadapted to be inserted or withdrawn as desired. Any number of theseplugs may be used as de is common.

As previously intimated, the side walls of the casing 6 may bediscarded, thus leaving the sides of the piston exposed, as with theproper packing of the peripherical casing the steam will be confined inthe piston-cham- I do not wish therefore to confine myself to the exactform or construction of the various parts illustrated and claim anychange therein that may be suggested by mechanical skill.

Having thus I'claim as new, Patent, is-

1. In a rotary engine a casing for the same having on different'parts ofits inner surface two or more channels a semicircumference or less inlength, a metal wheel-piston having in its periphery one or more groovesextending nearly around the same, a head in each groove integral withthe piston on the oppo site sides thereof, sloping walls in each grooveon each side of the head-extending from the bottom of the groove and ashort distance from the base of the head to the surdescribed myinvention, what and desire to secure by Letters to connect with thechannels in the casing as the piston revolves, steam-ports connected tothe channels in the casing, and exhaust-ports connecting with the groovein the piston, substantially as set forth.

2. In a rotary engine, a piston-wheel having grooves forming the steamchambers, each groove having a head, the heads in different planes ofthe piston, a casing for the piston, two or more channels in the surfaceof the casing between the grooves of the piston and in communicationwithsteam-ports and in communication with channels in the pistonconnected with the piston-grooves and opening therein on each side ofthe pistonhead, whereby each groove of the piston will, during a portionof the revolution of the piston be in communication with the livesteamports through the piston channels and easing channels with sliding gateto be actuated in and out substantially as set forth.

3. In a rotary engine having a piston-wheel having two or more groovesin its periphery forming steam-chambers, a casing for the piston havingtwo or more small channels on its inner circumference between the pistongrooves but not in communication therewith, each channel incommunication with livesteam ports and during a portion of therevolution of the piston, in communication with the grooves of thepiston with sliding gates in the casing to be actuated in and outsubstantially as set forth.

1. In a rotary engine, a piston having a steam-chamber extending nearlyaround the same formed by a groove in the piston, a head in thegrooveintegral with the piston, a casing for the piston having two ormore channels on its inner circumference not in direct communicationwith the steam-chamber but connected to live-steam ports, channels inthe piston on each side of the head adapted to connect with the channelsin the casing during part of the revolution of the piston and convey thesteam to the steam-chamber just behind the piston-head, and a gate inthe casing adapted to be actuated into the steamchamber and form a backstop for the steam, and means for throwing the gate in and out of thechamber substantially as set forth.
